PSA: Zarokh (4th asc trial) is impossible to beat with a cold build

Zarokh just innately has insane freeze resistance and takes quite literally around 5-6 minutes of spamming him with attacks until he gets frozen. Just by virtue of how frost spells work they do most of your damage when the target is frozen, you freeze them get a bunch of burst damage in and then you're back to dodging mechanics leading up to the next freeze burst.

For perspective all of the other bosses as soon as the fight starts I IMMEDIADLY get a full freeze on them with my combo and bring them to about 50% hp. The scorpion survives only one freeze and he dies on the second one. But then Zarokh is quite literally impossible, I can play the exact same way and he just doesn't build barely any freeze. This must be a gigantic bug, has anyone been able to beat him with a cold build?

For reference, I'm a level 85 cold spells blood mage. Yes, I'm aware they nerfed cast on freeze and my build isn't the best right now, but that's okay I've still been having a lot of success in tier 15 maps. Bosses are actually very easy for me and it's decent.

I want to add I've tried twice, the one time I had the 40% less damage buff and it was quite literally impossible. I had full honour going into the fight and I shit you not it took me fucking 5 minutes of fighting this guy to get 1 freeze on him. This HAS to be a bug. So I tried again, didn't have the damage buff but I had movement speed, but yeah I mean it still is completely fucked. He just literally takes forever to be frozen.

You might think "Oh maybe you need more freeze build up nodes" I HAVE ALL OF THEM. Every single freeze build up node that's decent I have in my build. I freeze shit immediately, EXCEPT this dude.

If you're a cold build, you have to do ultimatum right now until they fix this.

Please fix this GGG
